Spray paint gun head

Abstract

This invention relates to an improved pressure regulation structure at the tip of the spray gun connected to the nozzle. A screw hole is formed in the front section of a passage where a regulation shaft extends from the tip of the spray gun. An inner recess and an outer recess are formed on the front surface of the spray gun respectively with an air outlet. A gasket with slots is inserted between the spray gun and the nozzle. A hollow screwed tube formed in the rear of the nozzle to receive insertion of the gasket before being engaged to the screw hole of the spray gun. An inner recess and an outer recess with air ventilating holes and air outlets formed in the nozzle. A groove is formed around a nozzle tip at the front side of the nozzle. The inner and outer recesses of the nozzle abutted to the inner and outer recesses of the spray gun to form a pressure regulation air port; and outer threads provided on the nozzle to receive a nut for the spray head connected to a nut to hold against the nozzle.

I claim:  
     
       1. A spray paint gun head structure comprising a gasket, a nozzle, a spray head and a nut connected in sequence to the tip of a spray gun, wherein, a nozzle tip being formed in the front center of the nozzle; a groove with its outer surface formed a push-pull surface being provided around the nozzle tip; the spray head being engaged to a nut; the nut being engaged to the nozzle for a circular indention formed inside the spray head to hold against the front of the nozzle; a push-pull wall on the edge of the indention being abutted to the push-pull surface of the groove of the nozzle; air ducts connecting through outer air bases being provided on an outer ring around the push-pull wall of the indention inside the spread head, and a spray hole in the center of the front side of the indention to accommodate insertion of the nozzle tip, characterized by that: 
       a screw hole being formed in the front section of a passage where a regulation shaft extends from the tip of the spray gun to be engaged to the nozzle; an inner and an outer recess formed on the front surface of the spray gun respectively, each of the recess being respectively provided with an air outlet; a gasket being inserted between the front end of the spray gun and the nozzle; slots surrounding the center of the gasket at proper distance among one another being formed corresponding to the inner and outer recesses of the spray gun; a hollow screwed tube formed in the rear of the nozzle to receive insertion of the gasket before being engaged to the screw hole at the tip of the spray gun; an inner and outer recesses formed in the rear side of the nozzle; air ventilating holes connected through the groove being provided in the inner recess of the nozzle; a plurality of air outlets being provided in the outer recess of the nozzle; the inner and outer recesses of the nozzle abutted to slots of the gasket coupled to the inner and outer recesses of the spray gun to form a pressure regulation air port; and outer threads provided on the nozzle to receive the nut for the spray head to secure the nozzle in position by holding against the nozzle.
